Specification of Letters Patent.

Application filed February as, 1914.. Serial to. 821,828.

To all whom it may concern:

Be it known that I, Home J. MoMAoKIN,

a citizen of the United States, residing at.

Boston, county of Suffolk, State of Massachusetts, have invented anImprovement in Pasting-Machines, of which the followmg description, inconnection with the accompanying drawing, is a specification, l kecharacters on the drawing representing llke arts. p This inventionrelates to pasting machines adapted for applying paste to labels whichare to be subsequently applied to cartons, cans, boxes, etc., and theobject of the invention is to provide a novel device of this ciras whichis simple and inexpensive to manufacture, the parts of which can bereadily disassembled, thus facilitating greatly the cleaning of themachine and by which labels can be rapidly and efficiently supplied witha coating of paste, and otherwise to improve pasting machines, all aswill be more fully hereinafter described and then pointedout in theappended claims.

Figure .1 is a sectional view through a pasting machine embodying myinvention; Fig. 2 is a plan view of Fig. 1; Fig. 3 is an end view; Fig.4 is a section on substantially the line zva:, Fig. 3; Fig. 5 is asection on substantially the line y-y, Fig. 3;-

Fig. 6 is a fragmentary perspective view of the wiping pad.

The device herein illustrated is of that type which comprises a framesustaining a paste-receiving reservoir, a pasting roller journaled inthe frame and by which the paste is supplied to the labels or otherarticles to be pasted, a shaft situated above the pasting roller andprovided with disks that rest on the roller and which, serve to hold thelabel against the pasting rollerwhile it is being pasted, and means tooperate the roller and disk-carrying shaft.

In the drawings 1 designates the frame ofthe machine which is providedwith two end members 2 and which also is formed with a paste-receivingreservoir 3. I will preferably make the frame in the form of a castingso that the end members and the paste-receiving reservoir all formintegral parts of the same casting. The end members are each providedwith upwardly-direc'te'd extensions 4, each of which is provided with avertical slot 5, saidslots operating to receive both the shafts of thepastmg roller and that of the disk. The pasting roller is shown at 6, itbeing provided with journals 7 that occupy the slots 5, and theseournals will preferably be provided with collars 8 to hold the pastingroller against longitudinal movement. A This roller can be operated inany suitable way as by means of the handle 9.

10 designates the shaft which supports the disks 11 that bear on thepasting roller, the ends of said shaft 10 being received in the upperends of the slots 5. I will preferably provide means for positivelyrotating the disk shaft 10, this being herein accomplished by providingsaid shaft with a gearing 12 that meshes with a gear 13 rigid with thepasting roller 6. The frame 1 is so cast that the paste-receivingreservoir 3 is open at the top, and this opening is normally closed by acover 14 which also constitutes a platform on which the label to bepasted rests as it is fed into the machine. This cover may be held inplace in any suitable way as by means of spring catches 15.

In using a device of this sort, the label to be pasted is placed on theplatform or cover 14 with the face side up and the side to be pastedresting on the platform, and by turning the pasting roller the labelwill be drawn in between the roller and the disks 11, and the rollerwill apply a layer of paste to the back side of the label.

It is desirable that the peripheries of the disks 11 should be kept freefrom paste in order to prevent their depositing paste on the front sideof the label, and to thus keep them clear I propose to use a wiping pad16 which yieldingly engages the top of the disks and keeps theperipheries thereof free from paste.- This wiping pad is herein shown asmade of resilient material, such, for instance, as felt or rubber, andas confined" within a holder 17 herein shown in the form of-a tubewhichis cut away or slotted at one side, as at 18, to expose a portionof the pad 16. The pad 16 will preferably be so constructed that it willproject slightly through the slot 18 in the holder, and the i edges ofthe slots act as stops to prevent the pad from being brought against thedisks with undue pressure. and-its holder 17 are shown as carried byarms 19 that are pivoted at their ends to the frame at 20, and the padis yieldingly held against the disks by means of a spring 21 whichencircles the pivot screws 20 and en 27 on the end pieces 2 of theframe. By

means of this construction the platform can be swung back out of the waywhen the past ing roller is to be removed for cleaning or otherpurposes. This platform is yieldmgly and removably held in the notches26 by springs herein shown'as part of the springs 21. In other words,the spring wire from which the spring 21 is formed is extended at oneend, as at 28, and provided with a hook portion which hooks over thetrunnion 25.

The same spring, therefore, operates toholdthe platform in place andalso to yieldingly hold the wiping pad against the disks. The springs,however, can be readily disconnected from the trunnions 25 if theplatform is to be removed.

. a 29 designates a scraper which is adjustable toward and from thepasting roller and by which the amount of paste carried up by the rollerto the label can be regulated. This scraper is shown as pivotallymounted upon pivot pins 30 carried in the end pieces'of the frame, andit is provided with an extension 31 extending through a slot in theframe and engaging a groove .32 in an adjusting screw 33 that issituated exterior of the end piece and has screw-threaded engagementwith a lug 34 carried by the frame. By turning the screw 33 up or downthe scraper will be swung about its pivots, thus carrying its edgetoward and from the periphery of the pasting roller.

One advantage of my construction is that the shaft 10 carrying the disksand the pasting roller can be readily removed from the machine wheneverthe latter is to be cleaned, for it will be noted that both of these elements are journaled in the same open-ended slots 5, and are only held inposition by their own Weight and by the pressure of the wiping padthereagainst. The wiping pad can be readily swung back out of the wayafter which both the disk shaft 10 and the pasting roller can be liftedfrom the slots This pad 16 7 and cleaned, as also can thepaste-receiving receptacle. This is quite an important item in devicesof this class in which a sticky material, such as gum or paste, is usedfor unless they are frequently cleaned the machine soon gets gummed' upto such an ex tent as to render it unfit-for use.

My device is also well adapted for moistening gummed back labels.= Manylabels are supplied to the customer wlththe back already gummed and theoperation of putting the label on the box, carton or ackage involvesmoistening the gummed bac of the label. By filling the receptacle 3 withwater or some other moistening fluid, my device can be used formoistenlng gummed back labels.

While I have illustrated herein a selected embodiment of my invention, Ido not wish to be limited to the constructional features. shown.

Having described my'invention, what I claim as new and desire to secureby Letters Patent is 1.
